Attention: There are many different types of seals for plastic windows. Here you need to know exactly what you need. Because an unsuitable seal can lead to tensions between the window wing and the frame and subsequently damage to the fittings. If you are not quite sure, let the exchange be carried out by the specialist. Now you can attach the new seal. It is best to start in the middle of the upper frame and press the seal into the groove. At the corners, the seal is cut to miter. To do this, cut a triangular piece of approx. 10 to 15 mm width from the sealing foot (do not cut into the sealing surface). You can also cut the seal completely diagonally and stick it on the corners with a suitable sealing glue. If the seal is attached to Allen 4 window sides, they lengthen the loose end wit.
